Methods and challenges of a dementia prevalence study
NZSA2024
Claudia Rivera-Rodriguez, PhD
Found that the sampling/doorknocking strategy was reasonable
We were able to train up multi-ethnic interviewers
Response rate at the door-knocking stage was 75% but at subsequent stages was about 25%
Demonstrated that a prevalence study was feasible in Māori, Chinese, Indian and Pākehā, but not in Pacific populations.
Phase 1: Stratified by TA and rurality & oversampling of Chinese/Indian(65+) dense areas
Phase 2: Proportion of meshblocks sampled from each area – depends on the density of Chinese and Indian.
